A terrific new visualization tool for comet 67/P Churyumov-Gerasimenko demonstrates the value of sharing mission image data with the public. The browser-based tool lets you spin a simulated 3D view of the comet. It began with a 3D model of the comet created not by ESA, but by a space enthusiast, Mattias Malmer.

This month, at the same time that The Planetary Society is launching the long-anticipated LightSail prototype for a shakedown cruise, we are excited to launch another “first”—our first-ever Kickstarter campaign.

A new project—"Mars Academy"—aims to expand the cosmic horizon and offer a broader sense of opportunity for at least one group of underprivileged children in an impoverished neighborhood in Rio de Janiero, Brazil.

Seven possible interstellar dust grains have been found by Stardust@home, a citizen scientist project that The Planetary Society helped out early on. The dust grains would be the first ever examples of contemporary interstellar dust.

A new meteor shower, the Camelopardalids, will be peaking Friday night/Saturday morning (May 23/24). Especially if you are in North America, you are well positioned to see what may (or may not) be a spectacular show. In either case, scientists will learn about a comet’s history, and you can have a fun night looking at the sky.

Learn about the formation and origin of the Solar System and go beyond our neighborhood to investigate exoplanets (planets around other stars) in this video of class 11 of Bruce Betts' Introduction to Planetary Science and Astronomy class.

Would you like to be part of one of the largest citizen-science efforts in the history of astronomy? The International Occultation Timing Association (IOTA) invites you to join in the campaign to observe and time the best and brightest asteroid occultation ever predicted to occur over a populated area – and no telescope is required!

A coalition of grassroots pro-space advocates descended on Washington, D.C. this week, and held over 100 meetings with representatives and staff throughout Congress to argue for increased investment in NASA.

Juno's Earth flyby represented the first opportunity for many of the science instruments to be used on a planetary target. There were terrific photos of Earth and the Moon, plus a cool project to see if Juno could detect intelligent life on Earth.
